[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] In the description of the present utility model, it is necessary to understand that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1 As shown, the utility model provides an open-type headset, wherein the open-type headset is a smart headset, and the open-type headset can be configured with a call noise reduction function and / or an artificial intelligence noise reduction function, and at the same time, can also be configured with stereo surround and other functions.

[0034] The open earphone includes an ear hook 100, a metal shaft 200 and a sound unit 300. The metal shaft 200 is connected to the end of the ear hook 100. The sound unit 300 is connected to the metal shaft 200 and rotates with the ear hook 100 by means of the metal shaft 200.

[0035] It is understandable that the ear hook 100 is used to hang on the user's ear so as to wear an open-ear headset. Specifically, the ear hook 100 is a curved structure, and its shape is approximately U-shaped, which is convenient for hanging on the user's ear. When the ear hook 100 is hung on the user's ear, the sound unit 300 is opposite to the user's ear canal. In addition, the sound unit 300 can be rotated relative to the ear hook 100 by relying on the metal shaft 200, so that the user can adjust the angle of the sound unit 300.

[0036] like Figure 2As shown, the sound unit 300 includes a housing 310 connected to the metal shaft 200, a mainboard 320 disposed in the housing 310, and a metal bridge 330 disposed in the housing 310, and the metal bridge 330 is used to connect the metal shaft 200 and the radio frequency terminal 321 on the mainboard 320. It is easy to understand that the sound unit 300 also includes a speaker 340 disposed in the housing 310, and the speaker 340 is used to emit sound.

[0037] It can be understood that the housing 310 includes a first housing 311 and a second housing 312, and the first housing 311 and the second housing 312 are assembled to form a housing 310 with a hollow structure. The housing 310 is connected to the metal shaft 200 and can rotate relative to the ear hook 100 by relying on the metal shaft 200; specifically, the end of the ear hook 100 is connected to a support shaft, the metal shaft 200 is rotatably sleeved on the support shaft, and the housing 310 is fixedly connected to the metal shaft 200. The mainboard 320 and the metal bridge 330 are both arranged inside the housing 310, which can play a role of being protected. In addition, the metal shaft 200 and the metal bridge 330 both have conductive properties. By connecting the metal shaft 200 and the RF terminal 321 on the mainboard 320 using the metal bridge 330, the metal shaft 200 and the metal bridge 330 constitute an antenna that can radiate signals.

[0038] It should be noted that the metal bridge 330 and the metal shaft 200 may be connected indirectly or directly, but electrical conduction between the metal bridge 330 and the metal shaft 200 must be ensured.

[0039] In the open-ear headphones of the present invention, by replacing the existing shaft in the open-ear headphones with a metal shaft 200, and using a metal bridge 330 to connect the metal shaft 200 and the RF terminal 321 on the mainboard 320, the metal shaft 200 can be used as an antenna. The metal shaft 200 does not need to occupy the space inside the shell 310 when used as an antenna, which is conducive to the miniaturized design of the sound unit 300 and can ensure the length of the antenna, thereby ensuring wireless performance.

[0040] It should be noted that the materials of the metal shaft 200 and the metal bridge member 330 include but are not limited to copper, aluminum, steel, iron, etc.

[0041] Combination Figure 3 and Figure 4 In some embodiments, the metal shaft 200 has a first connecting portion 210 extending into the interior of the housing 310 , and the metal bridge 330 is connected to the first connecting portion 210 .

[0042] Specifically, the shell 310 is connected to the metal shaft 200, and an opening is provided on a side of the shell 310 close to the metal shaft 200, and the first connection part 210 of the metal shaft 200 extends into the shell 310 through the opening. In this way, the connection position between the metal bridge 330 and the first connection part 210 can be hidden in the shell 310, thereby achieving a protected effect.

[0043] like Figure 4 As shown, in some embodiments, the first connection part 210 is provided with a first assembly hole 211, the metal bridging member 330 has a second connection part 331, the second connection part 331 is provided with a second assembly hole 3311, and the sound unit 300 also includes a fastener 350 passing through the first assembly hole 211 and the second assembly hole 3311; wherein the first connection part 210 and the second connection part 331 are spaced apart, the fastener 350 is a metal fastener, and the first connection part 210 and the second connection part 331 are both in contact with the metal fastener.

[0044] It should be noted that the first connection portion 210 is a part of the metal shaft 200 and is also made of metal; the second connection portion 331 is a part of the metal bridge 330 and is also made of metal.

[0045] It can be understood that the metal fastener is used to connect the first connecting part 210 and the second connecting part 331 to achieve fixation between the metal shaft 200 and the metal bridge 330. In addition, the metal fastener is in contact with the first connecting part 210 and the second connecting part 331 respectively, so as to achieve electrical conduction between the metal shaft 200 and the metal bridge 330.

[0046] In addition, it is easy to understand that the metal fastener, as an intermediate component that electrically connects the first connection part 210 and the second connection part 331, can also be used as an antenna. The material of the metal fastener includes but is not limited to copper, aluminum, steel, iron, etc.

[0047] Further, the metal fastener can be operated to change the distance between the first connection portion 210 and the second connection portion 331. In this way, the length of the portion of the metal fastener located between the first connection portion 210 and the second connection portion 331 can be changed, and the length of the entire antenna structure can be changed so that the length of the entire antenna structure reaches an ideal length.

[0048] Specifically, one of the first assembly hole 211 and the second assembly hole 3311 is a screw hole, and the other is a through hole. The fastener 350 is a screw, which is inserted into the through hole and the screw hole. The screw can be rotated to change the distance between the first connecting part 210 and the second connecting part 331.

[0049] It is understandable that by rotating the screw, the distance between the first connection part 210 and the second connection part 331 can be changed, thereby changing the length of the portion of the screw located between the first connection part 210 and the second connection part 331, and thus, the length of the entire antenna structure can be changed so that the length of the entire antenna structure reaches an ideal length. In addition, by changing the connection position of the metal bridge 330 and the screw, and / or changing the connection position of the metal bridge 330 and the RF terminal 321, the length of the entire antenna structure can also be changed, thereby ensuring that the length of the entire antenna structure reaches an ideal length.

[0050] It should be noted that, according to the existing general technology, the condition that the miniature antenna design needs to meet is that the antenna length reaches or approaches one-quarter of the working wavelength. Only when the antenna length reaches this length will the radiation performance be greatly improved. Among them, the working frequency of Bluetooth is between 2.4Ghz-2.5Ghz, and its one-quarter wavelength is 20mm-25mm. Therefore, in this embodiment, the effective length of the metal bridge 330 plus the effective length of the metal fastener plus the effective length of the metal shaft 200 reaches 20mm-25mm, which can make the length of the antenna structure reach the ideal length.

[0051] Among them, the effective length of the metal bridge 330 refers to the length of the portion between the contact position between the metal bridge 330 and the RF terminal 321 and the contact position between the metal bridge 330 and the metal fastener in the metal bridge 330; the effective length of the metal fastener refers to the length of the portion between the contact position between the metal fastener and the first connecting part 210 and the contact position between the metal fastener and the second connecting part 331 in the metal fastener; the effective length of the metal shaft 200 refers to the length of the portion between the contact position between the metal shaft 200 and the metal fastener and the end of the metal shaft 200 in the metal shaft 200, wherein the end of the metal shaft 200 referred to here may refer to any one of the two ends of the metal shaft 200.

[0052] Please refer to Figure 4 In other embodiments, the first connection portion 210 is provided with a first assembly hole 211, the metal bridging member 330 has a second connection portion 331, the second connection portion 331 is provided with a second assembly hole 3311, and the sound unit 300 also includes a fastener 350 passing through the first assembly hole 211 and the second assembly hole 3311; wherein the fastener 350 is used to squeeze the first connection portion 210 and the second connection portion 331 together.

[0053] The fastener 350 is a screw, one of the first assembly hole 211 and the second assembly hole 3311 is a screw hole, and the other is a through hole. Of course, in other embodiments, the fastener 350 can also be a rivet, and the first assembly hole 211 and the second assembly hole 3311 are rivet holes.

[0054] It can be understood that the fastener 350 is used to connect the first connection part 210 and the second connection part 331 to achieve the fixation between the metal shaft 200 and the metal bridge 330. In addition, the fastener 350 is used to squeeze the first connection part 210 and the second connection part 331 together to achieve the contact between the first connection part 210 and the second connection part 331, thereby achieving electrical conduction between the metal shaft 200 and the metal bridge 330. In this embodiment, the effective length of the metal bridge 330 plus the effective length of the metal shaft 200 reaches 20mm-25mm, which can make the length of the antenna structure reach an ideal length.

[0055] The effective length of the metal bridge 330 refers to the length of the portion between the contact position between the metal bridge 330 and the RF terminal 321 and the contact position between the metal bridge 330 and the metal shaft 200 in the metal bridge 330; the effective length of the metal shaft 200 refers to the length of the portion between the contact position between the metal shaft 200 and the metal bridge 330 and the end of the metal shaft 200 in the metal shaft 200, wherein the end of the metal shaft 200 referred to here may refer to any one of the two ends of the metal shaft 200.

[0056] Please refer to Figure 4 In some embodiments, the inner wall of the housing 310 is connected with a positioning post, the metal bridge 330 is provided with a positioning hole 332, and the positioning post is passed through the positioning hole 332. In this way, the installation accuracy of the metal bridge 330 can be improved.

[0057] like Figure 4 As shown, in some embodiments, the RF terminal 321 of the mainboard 320 is in abutment with the metal bridge 330. In this way, the conductive cooperation between the RF terminal 321 of the mainboard 320 and the metal bridge 330 can be ensured, so that the signal emitted by the RF terminal 321 is radiated through the antenna structure.

[0058] In some embodiments, the metal bridge 330 extends from the metal shaft 200 toward the RF terminal 321 and continues to extend after contacting the RF terminal 321 .

[0059] It can be understood that, in the metal bridge 330 , the portion between the metal shaft 200 and the RF terminal 321 is used as the main antenna structure, while the other portions are used as auxiliary antennas to radiate signals.

[0060] like Figure 4 As shown, in some embodiments, in the metal bridge 330 , a portion between the metal shaft 200 and the RF terminal 321 has a bending structure.

[0061] It is understandable that by bending the metal bridge 330 between the metal shaft 200 and the RF terminal 321 , it is possible to avoid the metal bridge 330 being too long in a certain straight line direction, thereby preventing the volume of the sound unit 300 from becoming larger.

[0062] In the open-ear headphones of the present invention, by replacing the existing shaft in the open-ear headphones with a metal shaft 200, and using a metal bridge 330 to connect the metal shaft 200 and the RF terminal 321 on the mainboard 320, the metal shaft 200 can be used as an antenna. The metal shaft 200 does not need to occupy the space inside the shell 310 when used as an antenna, which is conducive to the miniaturized design of the sound unit 300 and can ensure the length of the antenna, thereby ensuring wireless performance.

[0063] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0064] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
